GRAIN-PICKLER.

To aZZ w hom it mayconcern 1 A Be it known-that .I, ARTHUR E. RooKoLA, a. subject of the'King of Great Britain,re-

. sidingat SandfordDeen, in the province of agitator causing the grain and solution deposited thereon to be thoroughly mixed and throwing the moistened grain into other receiving and discharging means, causing the grain and solution to be further mixed. Anotherobject of this invention is the production of a grain pickler wherein a'plurality of cones are positioned slightly below corresponding inverted frusto-conical collars so that grain'passing throughfthe casing will be thoroughly mixed upon engaging and disengaging these elements.

A still'further object of this invention is the production of'a grain pickler wherein the agitator has a plurality offfins thereon 'Aadapte'd to be; engagedby the grain to be efficientlyiotated for throwing the grain therefrom by centrifugal force, while the discharge nozzle is so arranged that the spray issuingftherefrom will also be dii'ectedonto the agitator tobe mixed with the grain as the same is being thrown therefrom. v I I A One practical 'form of construction and assembly of the present invention will be hereinafterdescribed, and is illustrated in the drawing,'in which: Figure 1' is a side'elev'ation ofjthe grain picklerjcomp'lete.

In; the preferred embodiment of the present nvention about; to be specifically described, the main supporting frame coinprises horizontal portions 10 having depending legs attheir ends. There are two of such port onsylO and. it will be noted that section taken on the line 55 the legs "11 of each portion are provided' Wlth a longitudinally extending brace 12.

Supporting bars 13 are carried by the horizontal portion 10 of the same as shown in Fig. 2, although a particular form of sup porting frame has been disclosed, it is obvious that any other desired or suitable form may be included without departing from the spirit of the present invention. A supply'tank 14 is secured as shown at 15 upon the horizontal portions 10 adjacent one end of the frame as illustrated in Figs. -1 and 2.v This tank may beof any desired construction and is provided with a cap 16. It. is intended that any suitable solution for treating the grain orpickliiig the same may be provided, such for instance, as. formalin which is carried within the tank 14 when the device is ready for use. The pipe 17 leads from the tank'a'nd passage through the pipe is controlled by a suitable valve 18 having a A second'pipe QOleading therefrom. A suitable union 21 isemployed for supporting and connecting the horizontal pipe'23 upon casing and hopper are eflic-iently'su )poi"ted upon the main frame of the device. The horizontal pipe 23 extends'througli the casing 25 intermediate its upper and lower ends as P v In order to regulate-the size of thecone of grain which is deposited upon'the rotary agitator tobe hereinafter described, there is provided a regulating cone 27 having a rod 28 extending from the apex thereof. The upper end of the rod is screw threaded as shown at 29 and is carried by the nut 30 mounted upon the transverse bridge 31 carried by the upper end of the hopper 24.

A crank 32 extends from the nut 30 so that by swinging the crank the nut 30 may be rotated upon the threaded upper end of the rod 28 for adjusting vertically the cone 27/ The stem 28 is also provided with a bearing 38 against which one end of the. coil spring 34 bears, the opposite end of the spring bearing upon the bridge 31 for yieldably holding the cone 27 in its lowermost position. In order to guide the movement or" the cone 27 a rocking loop 35 has one end pivotally journaled as shown at 36 within the casing 24, while the. opposite end of this loop 35 is carried by the cone 27 as shown at 37. Therefore the loop is pivotally mounted upon the casing and pivotally connected to the cone 27, thus allowing the cone to be moved upwardly or downwardly a slight distance as may be desired, although the cone 27 willbe held from swinging to one side by the force of grain falling thereon when the same is in use. The spray nozzle 38 is connected by joint 39 with the horizontal feed pipe 23 this spray nozzle has apertures 40 in its upper end, while a deflector head 41 is supported upon the upper end of the 'spraynozzle 3S and overhangs this end as shown inFig. 4.

It is to be noted that the lower end of the hopper 24 terminates adjacent the lower end of the head 41 whereby grain is discharged directly against the agitator, to be presently described.

The rotary agitator comprises a conical body 42 having its neck 43 embracing the nozzle 38. The base 44 fits within the lower portion of the conical body 42 as illustrated in Fig. 6 and is held against downward displacement by a bearing 45 carried upon the nozzle 38. It will be noted, however, that the rotary agitator is free to rotate upon the nozzle. A plurality of 'concaved fins 46 are fixed upon the upper surface of the conical body 42 as shown in Fig. 5 it being noted that these fins 46 are comparatively broad at their outer ends and taper toward their inner ends, as they extend toward the apex of the conical body 42 of the rotary agitator and are secured to the lower edge of the deflector 41. This rotary agitator is carried directly below the distributingcone 27 and for this reason as grain is discharged from the cone 2? it will strike the concavedfins 46 of the rotary agitator, thus causing the agitator to revolve upon the nozzle 38 thereby the grain will be thrown by centrifugal force from the agitator. At the same time the valve 18 may be regulated to permit the solution to pass from the tank 14 through pipes 17, 20 and the union21 and.

pipe 23 to the nozzle 38. This solution will be discharged through apertures 40 in a spray-like formation a ainst the under surface of the head 41 w ereby it will be defiected downwardly onto the rotary agitator to be thoroughly mixedwith the grain which at this time is causing the agitator to be reyolving and is being thrown outwardly from the agitator. A pair of spaced inverted substantially frusto-conical collars 47 are carried within the casing 25 below the pipe 23 as shown in Fig. 3. Supporting strands 48 are carried by these collars 47 and deflector cones 49 are carried by these strands 48, spaced from each other. The upperends of the cones extend into the lower portions of the collars 47 whereby grain discharged from the rotary agitator .will first pass through the upper collars and will then be deflected by the upper cones and subsequently will pass throughthe lower collar and then be-deflected by the lower cone and finally will be discharged from the lower end of the casing25.' Withthis torsional movement of the grain, which is being continually thrown-backward and forward and caused to rotate upon the inclined surfaces,

the grain will be eiiicientlyand thoroughly mixed with the solution directed into engagement therewith.-

When the device. is in operation, the tank 14 is first filled with a suitable solution, the

valve 18 at this time being closed. The device to all appearances will be the same as shown in'Fig. 1. It should be noted that the casing 25 is provided with a peepopening 25 adjacent the lowerportion of the hopper 24, thus allowing the operator to easily see the rotary agitator and to determine the .amount of spray being deposited thereon and also to determine the relative position of the distributing cone 27 with respect to the rotary agitator. The operator may then pour wheat into the hopper 24 and it will be noted that this wheat will strike upon. the distributer hood int 27 being distributed therefrom in a cone- 1 like formation. If the hood 2? be raised at. a considerable distance above the rotary agitator, the cone of grain will be comparatively large where it strikesthe rotary agitator although if the cone 27 be lowered, the cone of grain striking the agitator will be reduced. It is assumed that the position shown for instance in Fig. 3 would be about correct for ordinary operation. As this wheat or other grain strikesupon the rotary agitator it must engage the concaved .fins

46, thus rotating the agitator, Simultaneous with this action, the valve 18Twillhave been opened, thus causing the solution to be passedfrom the nozzle and deflected downwardly by the deflector head 41 onto the rotary agitator. This solution will be mixed with the grain which is then, falling onto thrown outwardly from. the agitator by,

centrifugal. force. This moistened grain will be caught by theupper collar and then fall therethrough onto the upper cone. This upper cone will direct the grain outwardly again to be caught by the lower collar, which in turn will direct the grain downwardly onto the lower cone'and thence the grain will be discharged from the casing. Thus if the grain being passed through the casing is not entirely moistened while on the rotary agitator, obviously the manner in which the grain will be turned over during its movement down from the casing will cause all surfaces to be exposed so that the surfaces will be effectively moistened by the solution. It will therefore be seen that a very efiicient grain pickler has been produced wherein the surfaces will be agitated to allow the solution to efficiently moisten the surfaces thereof as set forth.

The foregoing description and the accompanying drawings have referenceto what may be considered to be the approved or I desireit to be understood that I may make such preferred form of my invention.
